To all whom it may concern: 7

Be it known that I, REA P. WRIGHT, a citizen of the United States,residing at Washington, in the city of Washington, District of Columbia,have invented certain new and. useful Improvements in Pressure Releasesfor Clothes Wringers, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in clotheswringers and more particular to means for releasing the pressureautomatically on the abnormal separation of the rolls; the object beingto provide a positiverelease in which the rotation of the driving gearsof tuates the releasing members.

Another and further object of the invention is to provide a device whichis exceedingly simple and cheap in construction and one which can bereadily applied to the ordinary construction of clothes wringer now inuse.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings:

the rolls ac- Figure 1 is a side elevation of a clothes wringer showingthe application of my improved construction of pressure release thereto;

Figure 2 is an end view of the same; and

Figure 3 is a detailed view partly in section showing the manner ofconstructing the lower end of the pressure releasing member.

Like numeral of reference refer to like parts in the several figures ofthe drawing.

In carrying out my invention I employ a wringer of the ordinaryconstruction which comprises a frame 1 having slotted side bars in whichare mounted superposed pressure rolls 2 and 3 carried by shafts 4 and 5provided with meshing gears 6 and 7, one of said shafts being adapted tobe driven by any suitable means.

The pressure rolls are held under tension by pressure means comprisingthe usual pressure springs 8 and pressure bar 9, the latter beingengaged by pressure screws 10 carried by a top bar 11 movably mountedwithin the slotted side bars. By adjusting the pressure screws thetension on the pres- A," assrenoal'ro Jenni sure rolls canbe adjustedthrough the pres-v sure means in the ordinary manner.

Secured to each of the side bars of the frame is a bearing plate 12which extends across the slot thereof and is provided with a stud shaft13 on,which is pivotally mounted a lever 14 which is provided with ahook portion 15 at its upper end adapted to engage a pin 16 carried bythe end of'the movably mounted top bar 11 for holding the top bar in apredetermined position in order to allow the pressure to be maintainedand adjusted on the pressure rolls. a

The lower end of the lever 14 is slotted as shown at 17 through whichextends a pin 18 carried by a cap 19 which is held in position as shownin Figs. 2 and 3 by a pring 20 in order to provide a yielding contactportion for the lever so that when the gear is moved upwardly by theabnormal separations of the roll, the lever will be prevented from beinginjured. The normal position of the lever 14 is out of a vertical planeso that the same extends obliquely across the slot and to one side ofthe center of the gear. When a foreign object is drawn between the rollsso asto separate the same abnormally, the gear 7 is moved upwardly andas the same is being constantly rotated the teeth thereof engage the capof the lever and rock the lever on its pivot 13 so as to move the hookportion 15 out of engagement with the pin 16 carried by the movablymounted top bar in order to release the pressure from the pressurerolls.

While I have shown a yielding member carried by the lever this is notessential, as by mounting the lever obliquely the gear will engage thesame in such a manner as to swing the lever on its pivot as the same isrotating.

I claim: a

1. A clothes wringer,.comprising a frame having pressure rolls andpressure means for said rolls mounted therein, a top bar movably mountedin said frame having means for adjusting said pressure means.

gears carried by said pressure rolls, and" levers mounted on the sidebars of said frame for holding said top bar in predeterrained positionwithin said frame, said levers being engaged by the gears of the movablepressure roll on the abnormal separation of said rolls for causing saidlevers to be oscillated by the rotation of said gears for releasing saidtop bar.

2. A clothes Wringer, comprising a frame having pressure rolls andpressure means for said rolls mounted therein, a top bar movably-mounted in said frame, levers said levers being provided with movablemembers, said qmovablemembers being engaged by the gears of the movablepressure roll on the abnormal separation of said rolls for causing saidlevers to be moved out-of engagement with said top bar by the rocationof said gears.

Intestimony whereof I hereunto affix my signature.

a REA P. WRIGHT.
